To all whom it may concern:

Be it known that I, Ronnn'r ANDERSON, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Reinforced Concrete Construction for Buildings, of which the following is a specification.-

My invention relates to that class of reinforced concrete building construction, wherein the place of beams and girders is taken by a net work of rods, which extend transversely, longitudinally and diagonally from column to column, and are supported by rings carried by the downturned ends of the column rods. In this class of construction it has been customary to extend each rod across the column. As a result such a mass of metal was concentrated over the top of the column, in order to resist the negative moment, that there was too little room there between the rods for concrete, and great difficulty was experienced in properly surrounding the rods there with concrete.

The object of my invention is a reinforced concrete construction of the class described, but in which there is ample room for concrete over the column and also-means for resisting the negative moment. This object 1 attain by the means described in the specification and illustrated in the drawings, in which,

Figure 1 is a vertical sectional View of the top of a column and part of a floor embodying my invention. Fig. 2 is a detail plan view of the metal in position, upon the column rods, preparatory to receiving concrete.

leferring to the parts :The column consists of the'usual vertical rods A, which are surrounded by metal bands at, and are down turned at their upper ends a, to form a support for strong metal rings B B. At the top of the column are longitudinal rods D and D, transverse rods E and E, and diagonal rods F F and G G. Longitudinal rods D, transverse rods E, diagonal rods F and. diagonal rods G, are bent upward and continue over the top of column. Longitudinal rods D, transverse rods E, diagonal rods F and diagonal rods G, alternate with longitudinal rods D, transverse rods E, diagonal rods F and diagonal rods G, respectively.

The rods D, E, F, G, have hooks d, e, f, g, respectively, at their ends. Said hooks embrace the rings B B and have their upper ends adjacent to the upper surface of the concrete, which is filled in readily around the rods over the columns.

In use :The tension of the rods D, E, F, G, is transmitted to the rings B B, so that the tension of the hooked rods upon one side of the column is opposed to the tension of corresponding rods on the opposite side of the column. Rings B B'and the upper ends of the hooks likewise take up other tensions and stresses, which occur within the area, adjacentto said rings, and hooks.

hat I claim is 1. A reinforced concrete column and floor construction consisting of vertical reinforcing members in the column, a ring surrounding and supported by the vertical reinforcing members, tension members hooked around the ring terminating at the ring and radiating from the ring thereby leaving room for concrete between the ring and the vertical reinforcing members, and a series inverse tension members crossing the ring.

2. In a reinforced concrete construction, the combination of a column having vertical rods downturned at their upper ends, a ring supported by the upper ends of the column rods, a series of transverse, of longitudinal, and of diagonal rods, some of the rods terminating at the rings radiating therefrom and having hooks at their ends embracing the ring, and the other rods of said series extending over the column, and concrete embedding the rods, hooks and ring.

3. In a concrete construct-ion, the combination of a column having vertical rods, a ring at the top of the column and surrounding the rods, a series of transverse and of longitudinal rods, alternate rods of each series extending over the tops of the columns, and the intermediate rods termirating at the ring and having hooks at their ends embracing the ring and concrete surrounding the rods, hooks and the ring.

' 4. In a concrete construction, the combination of a column having vertical rods the ring and having hooks at their ends downturned at'their upper ends,a ring snpembracing the ring, and concrete embedported by the downturned ends, a series of ding the rods, hooks and ring.
